How Many Stars Are There?

this video was just beautiful.

I will never get tired of having the scale of the universe put into perspective. Fantastic video!

This was beautifully done, Joe!

NEW VIDEO! How many stars are there? 

A friend of mine asked me, “How many stars are there?” I said, “Let me look that up for you.” He said, “In a book?” I said, “No, in the sky. Never believe what you read.”

I love the feeling I get while learning about galaxies and space! Thank you for this video.

Can't figure out which blows my mind more; the huge number of stars that exist, or the tiny number that we can see, and which SEEMS so vast. I mean, I could count to 9,096. I take more steps than that in two days of running. This seems as strange to me as the septillion stars, which, as you said, is a number that we can't even make sense of. Thanks for giving me much to think about as I have to go do some tedious chores now.

Man, wish this video was longer, so beautiful...

Am I the only who thought of "my god it's full of stars" at 1:18

Haha, Youtube's compression didn't really handle all the stars too well! :-)

Re-watching older videos while stuck home. Anyway, this really reminded me how much I miss living in the desert, far from any major light pollution (even the couple closest were far, an rather dim compared to many places) where I could get an absolutely stunning view of the night sky. Even in winter at temps below freezing I would occasionally spend a night laying on a trampoline. With blankets, pillows and whatnot to stay warm, as well as snacks, water, etc. of course. Being above ground level was nice to limit critters looking for warmth- though it didn't exactly help keep me warm. But with the right supplies and covers, it was my favorite choice. Absolutely fantastic views of stars, and the milky-way, surrounded by occasional howls of coyotes, and the wind; truly a grand experience. I'd be lying if I didn't say I also usually brought out some music to listen to at times. With or without it was an experience I plan to have again, and can't recommend enough. Even when freezing (especially on the rare 'bathroom' trips) it was definitely worth it.

Last week I watched my first video of yours, and since then I'm just really fascinated about knowing such sciences.... And as I'm a science student I can say you can really explain things very very correctly... Great work

thank you so so so much for these AMAZING videos! it's so hard to pick a favourite! I know that you are actually doing this for (high) school students, but I am a "scientist" (psychologist), almost 40 years old and still just LOVE these clips!!! Thank you, Thank you, Thank you!!!

This truly was a amazing. 200 billion galaxies? That's too mind blowing. I thought there were only 1-100

First video I've seen on this channel. Really well done and informative! Thanks!

Ok, so how much sand if every star is a grain of sand? Turns out, it's over five times the volume of the sun or 7.4 * 10^33 cubic meters. That's a lot of beaches. Fun fact, as Wolfram Alpha tells me, this volume is only 0.16% the volume of Betelgeuse. That's one way of saying that Betelgeuse is kind of big I guess. No, you still only get one grain of sand, Betelgeuse! Don't you look at me like that, with a septillion stars, there is no special treatment.

I love talking about this when I do shows at the planetarium and they get to see 5 projectors on a huge dome, full of stars. Then I show them what our sky would look like with all stars within 100 light years, then show them the Hubble deep field to really set the scale of what's really out there.

It only took one day to make all those stars but the earth took a whole three. Sounds legit.

Very nice job man ! Your channel is my discovery of the day, and the video is great. Subscribed ;)

Awesome video. The universe is truly amazing. As a kid I loved everything that had to do with stars and planets.
